Need to deal with half-dead tservers
------------------------------------
Key: ACCUMULO-513
URL: https://issues.apache.org/jira/browse/ACCUMULO-513
Project: Accumulo
Issue Type: New Feature
Reporter: Keith Turner
Fix For: 1.5.0
Every once in a while a tablet server will go zombie. The tablet server is
alive and talking to the master and zookeeper, but not accepting new
connections from clients. To keep these types of tablet servers from causing
problems a process could try to scan a tablet on each tablet server
periodically. If it can not scan a tablet within a certain number of tries, it
could delete the tservers lock in zookeeper. The monitor process could do
this.
